  "country": "US",
  "title": "How Wearable Devices Use Location and Biometrics to Know Who You Are",
  "original_title": "Speech based user recognition",
  "summary": "This patent describes how a computer system can figure out who is using a wearable device by combining its location data with biometric information like a face scan or voice recording.",
  "what_it_does": "The patent describes a computer-implemented method (Claim 21) for identifying a user of a wearable device. It works by receiving two types of data: first, location data for the wearable device (Claim 21), and second, biometric data such as image data of a face or audio data of a voice (Claim 21). The system then processes both the location data and the biometric data together to determine the user's identity (Claim 21). For example, if a smartwatch (wearable device) is detected in a specific room in a house (location data) and then records a voice command (audio data), the system can use both pieces of information to confirm if the voice belongs to the known owner of that smartwatch, especially if that owner is typically in that room. The system can also use a known user's profile to compare the biometric data (Claim 22, 23) and consider the type of wearable device (Claim 29) to improve accuracy.",
  "what_it_does_not_cover": [
    "Does not cover user identification solely based on biometric data (e.g., just a fingerprint scan) without also using location data or device type.",
    "Does not cover systems that identify users without involving a \"wearable device\" as defined by the claims.",
    "Does not cover identification methods that rely only on a user's password or PIN without any biometric or location input.",
    "Does not cover systems that determine identity without combining at least two distinct data types: location data and biometric data (image or audio)."

  "abstract": "Systems, methods, and devices for verifying a user are disclosed. A speech-controlled device captures a spoken command, and sends audio data corresponding thereto to a server. The server performs ASR on the audio data to determine ASR confidence data. The server, in parallel, performs user verification on the audio data to determine user verification confidence data. The server may modify the user verification confidence data using the ASR confidence data. In addition or alternatively, the server may modify the user verification confidence data using at least one of a location of the speech-controlled device within a building, a type of the speech-controlled device, or a geographic location of the speech-controlled device.",
